FREDERICK KNOWLES, or HARTFO D,connnccrxcur METHOD OF PRODUCING SHADED EFFECTS IN DESIGNS.

Application filed August 25, 1913.

To all whom it may concern Beit known that I, FREDERICK KNOWLES, a subject of the King of Great Britain, residing at Hartford, in the county of Hartford and State of. Connecticut, have invented certain new and useful Improvements in Methods of Producing Shaded Effects in Designs, of which the following is a specification;

This invention relates to a method of producing shaded effects in designs.

At the outset I wish to make it clear that I employ the term design in a broad sense, to include pictures, portraits and all like things made by hand or otherwise which are susceptible of being shaded. In like fashion the shading may be of any character, for example stippled, lined, stippled'and lined or solid, these being merely several illustra tions. By the method I can secure in a quick, inexpensive and eiiicient manner shaded effects or areas. The invention probably as to its broadest aspect comprises the super-posing of a design and a shaded transparent sheet. I obtain the best effects by laying the shaded sheet. directly upon the design. The sheet in question may be of any desirable character, and when I say that it is transparent, I mean substantially so, although the best effects are secured by having the sheet actually transparent. It might be sufliciently translucent, however, or semitransparent to be not objectionable or to an extent sufficient to freely perceive or to be [able to photograph without bad effects, the design back of the transparent sheet. This sheet may be made from any desirable material. I have secured excellent effects by making it of comparatively thin celluloid, land in this way I secure transparency, lightness and flexibility, the latter being of advantage, in that the sheet can be-carried in roll form. I prefer also that the sheet be of a substance that can be easily and readily cut as distinguished from glass which necessitates the use of a special implement for cutting it. Transparent paper also answers my purpose, although it is not as desirable as the sheet cellulold, but it has the advantage 5b lof being readily and easily cut. The celluloid or other sheet has formed on it in any desirable way for example by printing or by hand, the shading, and as already observed this shading may vary decidedly as to lcharacter, and the shading maybe made thereon in any suitable way for example by Specification of- Letters Patent.

printing. It will be supposed that there is presented a non-shaded picture such as used in advertising Work and that it is desired that this picture be shaded by my method for example by stippling throughout its entire surface. In this event the picture is laid against a background, for example a board and if necessary fastened thereto by thumb screws or in any other convenient manner. The transparent shaded sheet is then laid directly over the picture, and is if required fastened in place for instance by thumb of a building and that he desires the sky to be stippled or any other part to be otherwise shaded. In this case the picture may be attached to a suitable foundation and the shaded transparent sheet laid thereover as before set forth. It should be explained that in each of the cases the shaded side of the sheet is up or exposed, although there may be instances where this is not necessary, but Where only a portion of the finished picture should be shaded it is preferable, although not essential, that the shaded side of the sheet be up, theadvantage being the facility with which the shaded surface can be obliterated by erasure or by painting or covering the shaded surface. Proceeding with the second example, the artist with the aid of a suitable implement for example a sharp edged instrument or even a rubber eraser, removes that part of the shaded sheet opposite that area of the picture which should not be shaded. After this is done the picture with the superimposed transparent feet. In this event the work may have to be done over again or if not this, considerable labor will be involved in getting the desired effects, whereas by laying a shaded sheet over the outline or non-shaded picture and then obliterating portions of the shading, the ultimate effect can be at once determined. Of course, the advantages of my method of procedure are at once obvious oyer this old laborious method. 4

I am familiar with another method which is practicallyas follows. The artist has his non-shaded picture and is provided with a transfer sheet by which the shaded effects are to be secured. In this second old method the portions of the picture which do not require shading are covered and the transfer sheet is laid over the picture and the shading by rubbing the back of the transfer sheet, is applied to the picture. The artist in this particular instance, however, cannot see the effect desired until the picture is finally shaded, whereas by my method he can merely lay the transparent shaded sheet over the picture and determine at once before the outlay of any effort or time just what the results are to be Without changing, spoiling or defacing the picture and by the expenditure of a-little effort and labor,

where portions are not to be shaded can without'making a mark on his picture, ascertain the efl'ects.

In the drawings accompanying and forming part of the present specification I have shown one of the several ways of carrying the method into .eifect,"=and in these drawings,

Figure 1 is an illustration of a picture; Fig. 2 is a view of the picture with the transparent shaded sheet placed thereover with none of the shaded surface removed, and F ig. 3 is a view similar to Fig. 2 with portions of the shaded surface of the transparent sheet removed.

The numeral 1 is supposed to represent a picture. In Fig. 2 it is shown as having the transparent shaded sheet 3laid thereover, none of the shaded area, however, being obliterated. In Fig. 3, however, a portion of the shaded area of said transparent sheet is obliterated.

What I claim is:

1. A method of the class described comprising positioning a shaded, transparent sheet in front of a se.ond sheet having a design thereon, to produce a composite sheet, obliterating a portion of the shading of the shaded sheet, and then photographically reproducing the composite sheet.

2. A method of the class described, comprising positioning a shaded, transparent sheet in front of and directly upon a second sheet having a design thereon to produce a composite sheet, obliterating a portion" of the shading of the shaded sheet, and then photographically reproducing the composite sheet from the transparent sheet side of said compdsite sheet.

In testimony whereof I aflix my signature in presence of two witnesses.
